From publisher blurb:
Unleash Your Hunger!
Come discover the secrets of the rakshasa. They are hunger made manifest, insatiable earthbound spirits born in blasphemy. Be the apex predator slipping unseen among the mortal masses, befuddling their mind, senses, and emotions while you dine on all the physical and spiritual tastes the mortal world can offer.
Play the 1st-20th level rakshasa paragon class that allows you to eventually become a Rakshasa Maharaja! Create the rakshasa you want to play right alongside all the dwarven fighters, the elven wizards, and human barbarians, in the Pathfinder Roleplaying Game.Choose the native outsider race the yaksha, with its racial traits, alternate racial traits, favored class bonuses, and racial feats that will allow you to play minor rakshasa with any base class. Select from among the racial archetypes for the Monk, Slayer (Advance Class Guide), and The Luckbringer (Rite Publishing’s The Secrets of Adventuring) so you can bring the true nature of the rakshasa to bear.
Now come and play a Rakshasa!
